Check Digit Verification of cas no
The CAS Registry Mumber 22167-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,6 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22167-05:
(7*2)+(6*2)+(5*1)+(4*6)+(3*7)+(2*0)+(1*5)=81
81 % 10 = 1
So 22167-05-1 is a valid CAS Registry Number.
